To all whom it may concern:

Be it known that We, JOHN ENGLAND, a resident of London township, andMOSES HUTOH- INSON, a resident of the city of London, in the county ofMiddlesex, in the Province of Ontario, Canada, subjects of the Queen ofGreat Britain, have jointly invented a certain new and usefulImprovementin Seat-Posts for Bicycles, of which the followingspecification, taken in connection with the accompanying drawings, formsa full, clear, and exact description.

This invention relates to an improvement in seat-posts for bicycleswhereby they may be adapted to be used as a carrier or receptacle forthe bicycle air-pump, repairing material or tools, or other merchandise,parcels, or articles, the object being to so construct the vertical orhorizontal portions of a bicycle seat: post and a receptacle containedtherein that the latter may be readily, easily, and instantly removedfrom or secured in place in the former; and this invention consists inthe novel construction and combination of parts, as will be hereinafterfirst fully set forth and described and then pointed out in the claims,reference being had to the accompanying drawings, Wherein Figure 1 is aside elevation of a seat-post embodying our invention. In this view theseat-post mast is shown in section and the adjacent parts of thebicycle-frame in dotted lines. Fig. 2 is a central sectional View ofsame. Fig. 3 is adetail central sectional view of a receptaclecontaining a bicycle repair outfit and wrench. Fig. 4 is an enlargeddetail side View of the horizontal portion of the seat-post, a portionof one end of which as well as the receptacle and securing devicescontained therein are shown in section. Fig. 5 is an end view of Fig. 4.Fig. 6 isa crosssectional view on the line a: 00 of Fig. 4:. Fig. 7 is adetail frontand side view of the springbolt. Fig. 8 is a detail sideview of the horizontal portion of the seat-post, partly in section. Fig.9 is a detail side View of the re ceptacle, partly in section.

In the accompanying drawings, A designates the seat-post mast, B the topbar, and O the back stays of a bicycle-frame.

said seat-post.

D designates the seat-post, consisting of the horizontal portion D andthe upright portion D designates a groove or recess formed in theinternal face of each of said portions D and D as shown particularly inFig. 8.

E designates a receptacle, and E a partition therein, which divides saidreceptacle into two chambers e and c and e is an elongated slot in theend of, and c an opening in the side of, said receptacle.

F designates the cement, G the repairing material, and H a wrenchcontained in one receptacle, and I an air-pump contained in the otherreceptacle.

J designates a spring-bolt, which is located in the chamber e of thereceptacle E, the reduced outer end of which bolt J extends through theopening e in the side of said re ceptacle,and J is a pin which extendsthrough the elongated slot e in the end of said receptacle, and itsinner end is rigidly secured in the spring-bolt J, and J is a socketformed in, and J a shoulder formed on, said springbolt.

J designates a coil-spring located in the chamber e of the receptacle E,between the spring-bolt J and the inner face of said receptacle, andsaid spring J is held in line as said spring-bolt is moved back andforth by being located in the socket J in said spring bolt.

' When the various parts are placed in position, as shown in Figs. 4 and6, the outer end of the spring-bolt J is held by the spring J in thegroove or recess D in either the horizontal or vertical portion of theseat-post D to safely and securely hold said receptacle,

as well as the articles contained therein, in Again, by pressing on theenlarged head J of the pin J and moving the latter toward the center ofthe receptacle E the spring-bolt J will be moved in the same direction..This will withdraw the end of said spring-bolt J from the groove orrecess D in the horizontal or vertical portion of the seatpost andcompress the spring J permit the receptacle E to be readily, easily, andinstantly removed from the seat-post in order toget access to theinstruments in said receptacle E, and when through with said in- T1118will Ipo struments by replacing them in said receptacle E and insertingthe end of the latter in the hollow portion of the seat-post andpressing on the enlarged head J of the pin J, as just described, the endof the spring-bolt J will be moved into the chamber e of the receptacleE and the spring J 5 compressed, so that when the receptacle E has beenadjusted to the position shown in Fig. 4 by releasing the head of thepin J from pressure the spring J will expand and move the end of thespring-bolt J into the groove or recess D in the seat-post D.

The advantages of this invention are that the automatic locking devicesbeing located in the end of the receptacle and seat-post very littleroom is occupied by them. Therefore the full capacity of the receptaclemay be utilized; and, again, the partition in the end of the receptacleprevents the instruments or other articles contained therein frominterfering with the free Working of the automatic fastening devices.Again, the whole is concealed within the seat-post and carried by thebicycle, and a simple, strong, durable, and inexpensive device for thepurposes described is provided.

Having thus described our invention, we claim In a device of thecharacter described, a receptacle, in the side and end of which anopening and elongated slot respectively are formed, a partition in saidreceptacle for dividing it into two chambers, a spring-bolt formed witha shoulder and in which a socket is formed, one end of which spring-boltprojects through the side opening in said receptacle, a coil-spring insaid receptacle located between said spring-bolt and, the adjacent faceof said receptacle, a pin secured to said spring-bolt and extendingthrough the elongated slot in the end of said receptacle, in combinationwitha bicycle seat-post, in the interior face of which a circumferentialgroove is formed, with which the end of the springbolt engages,substantially as and for the purpose set forth.

In testimony whereof we have signed in the presence of the twoundersigned witnesses.
